Fig. 3 is a sectional view taken through the tire structure and theadjacent Wheel rim illustrating one of the lateral inclined expansiblemembers;

Fig. 4 is also a sectional View taken through the tire structure and theeoacting wheel rim showing a second form of lateral inclined eXpansiblemembers `as herein included; and

Fig. 5 is a fragmentary sectional view taken substantially on the line5-5` of Fig. l.

Dis` posedf` through adjacentextensions or ears 3 "f v are the clamping n the metallic i theaccompanyingdrawstraps 2 terminating in the outwardly di` bolts lwhereby it will be perceived that -the^ring member-S"may-be 1-readilyand` egectively clam oil fellvlt or removed therefrom When thenecessities of practice so necessitate.` I have ped` to the rimw alsofo'undl` that the sections 1l ofthe ring i @member S may loe-made ofWood.

C denotes the carcass `of Vmy improved tire which is preferably Iformed`of thin resilient metalf and providedfivith an `outer cover- 3' ingorlamination G `of rubber.

t The carcass @is of conventional form `in rross `section and `has itmarginal `portions I`I Y' overlying the! side faces of the member'SlSecuredto the'inner face Lof `the carcass@` 1^ at the tread portionI*thereof andy in prede l* ftermined circumferential spaced'relatioirarethe plates havingpressed"outwardly there- 1 from the protuberances orIlugs 8 with Which coact the i you ter end portions of the `radialexpansible members wherein"disclosedas conventioiialrcoil springs.` Theopposite 'end portions of the expansible members 9*are' operativelyengaged tion of the member "bers 9 serve to compensate for the direct orradial strain imposed upon the tire.

I also find it of advantage to provide the inner face of the carcass Cat predetermined intervals and at opposite sides of its tread portionwith the additional plates l() also having pressed therefrom theprotuberances or lugs 1l with which are operatively engaged theexpansible members l2 also preferably embodying coil springs. TheeXpansible members 12 are disposed on predeten mined inclines laterallyof the member S and have their inner ends operatively engaged therewith.The expansible members l2 serve to compensate for the lateral strainimposed upon the tire.

Additional plates 11i are arranged in pairs adjacent the coacting endsof the sections l of the member S and the plates 14 of each pair are inpredetermined circumferentially spaced relation as particularly with theperipheral. porber 16 disclosed as a conventional coil spring` and whichhas its inner end portion operatively engaged with a section 1 and it isto be noted that the member 16 is inclinedinwardly relative to the endof the coacting section 1 of the member S and servesto compensate forcircumferential movement of Varearranged -indicated at18 invdetail Fig.5, and coacting withl said overlying portions 18 is the secur thecarcass C. Y

vI have also found it of advantage to dispose within each of theeXpansible members or springs 9, 12' and 16 a core 17 of rubber which"serves ltol materially .facilitates the cushioning action imposed uponthe carcass C. Each of the sections of the carcass has a radial vspring9 positionedV substantially central thereof with circumferentiallyinclined springs 16 adjacent the opposite ends of'the section.intermediate each of the springs 16 vand the central or radial 1 ispring9 is a spring 12 and the spring 12 at one sidev of the spring 9 isoppositelyinclined relative tothe second spring 12.y Y

Ithas also been found of advantage lto form the metallic portion 5 ofthe carcass C in sections also preferably four in number. Theadjacent'end portions of the sections in overlying relation as clearlying member 19 herein set forth as a headed member loosely disposedVthroughthe outer overlying portion and` inthreadedengagementwith theinner overlying portion.

f From the foregoing description, it is thought to be obvious thataftirevstructure vconstructed in accordance withvmy invention is ofanextremely simple and comparatively inexpensive nature and isparticularly Copies jf'tiis patent may be obtained for Vvention inpractice,

well adapted'for use by reason of the con` venience and facility withwhich it may be assembled, and it will also be obvious that my inventionis susceptible of some change and modification without materialdeparture from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my ineXcept as hereinafter claimed.

I claim:

In combination with a wheel, a ring member disposed circumferentiallytherearound, a substantially hollow carcass formed of resilient materialand co-acting with the ring member, said carcass being dividedcircumferentially 'into sections, a radially disposed expansible memberinterposed between the ring member and the tread portion of each section,of the carcass at substantially the longitudinal center of the carcass,eXpansible members interposed between the ring member and the oppositeends of each of the sections of the carcass, saideXpansible inembersbeing `inclined circumferentially in a direction away from the ends ofthe sections, and laterally inclined expansible members interposedbetween the ring member and the carcass at opposite sides of theradially disposed expansible member of each section, the relation of thelaterally inclined expansible members yof each section to each otherbeing in outward divergence.

In testimony wtliereof I hereunto affix my signature in the presence oftwo witnesses.
